VACUUM IMPREGNATION OF WINDOWS-FRAMES, SHUTTERS, DOORS, AS WELL AS LOOSE ELEMENTS – IMP-PG series – As per E.C. rules
The realisation of mod. IMP-PG vacuum impregnation plants, designed to operate using a limited quantity of impregnant contained in the plant, has enabled firstly, the clear or coloured application of impregnants to be used followed by primer and finish coatings.
The plant, hermetically closed and operating automatically, eliminates the necessity for:
a) Specialised personnel
b) Expensive equipment for treating and filtering of waste from coating
c) More coating product to be used than is necessary
d) Expensive controls to guarantee a constant quality level

Furthermore it guarantees:
1. The use in the same plant of a wide range of impregnants for the protection or treatment against woodworm, termites, fungi etc., for wood subjected to Risk Class 1, 2 and 3
2. Perfect homogenous protection against the sun’s rays
3. Protection against humidity and water: the perfectly homogenous application waterproofs up to the last micro-pore and makes the wood water repellent
4. A new coating process, which gives a perfectly homogenous application and a total penetration of the resin in the joints, cracks and weak areas which when using other processes do not receive protection
5. The fixing characteristics regarding the application of coating products in the absence of air using ultra high vacuum (vac-vac) enable penetration into the smallest of pores, reaching a durability level 3 to 4 times higher than normal coatings
6. Maximum bond between primer and finishing coat
7. Significant reduction in surface preparation time after applying the primer thanks to the reduced “lifting of skin” phenomena
8. Recovery of the entire unused product
9. There is no waste of product.

THE WOOD IMPREGNATING AND COATING SYSTEM IN AUTOCLAVE
The plant is made up of a very particularly thick autoclave (1) so as to support a maximum vacuum of 400 mmHg or 700 mmHg.
The elements to be treated are loaded and positioned on a moving frame (18) equipped with a trolley, which moves into the autoclave on rails held internally at the top and bottom.
At the bottom of the autoclave there is the deposit (2) containing 70 to 100 litres of impregnant or coating. A pump (4) pumps the product to a series of atomiser outlets (7) placed in a star formation on a frame (6) which moves horizontally forth and back along the whole length of the autoclave.

A standard treatment cycle lasting about 20 to 30 minutes, is as follows:
A – An initial vacuum phase to remove all air from the wood pores.
B – Treatment of items, with impregnant or finely atomised coating. During this phase the plant can operate both under constant vacuum or allowing air to enter to help the product penetrate deeply into the wood.
C – A series of changes of air inside the autoclave to facilitate dripping, drying and pacifying of the treated items.

This treatment guarantees:
When using impregnants: An absorption / penetration of 3 to 6 mm. In the white part.
When using primer/finishing coats: A very high penetration and adherence level of the coating to the internal surface of the wood pores, a result that can only be achieved thanks to the vacuum.
The exceptional penetration and adherence of the primer is the only guarantee for a perfect and lasting resistance of the finishing coat, both if applied using the same plant or using other techniques.
– Result guaranteed: Thanks to the completely automatic operation of the machine, any possible human error is excluded.
Maximum respect of the environment The vacuum pump, which sucks in the air in the autoclave, is the liquid ring type: it also uses water in a closed circuit.
The impregnating and coating system operates in a perfectly hermetically closed autoclave that prevents any type of bad smell from exiting. Once the process has finished the product may be fully recovered by sending it back to the relative deposit.
The water used for washing the air entering the plant will be continuously recycled and periodically it must be discharged and changed. During drying the water may contain polluted substances made up principally of chemical products used in the coating products.
The autoclaves are built on the basis of the sizes of the items to be treated.
The items exit the autoclave perfectly dry, treated or coated.

THE VACUUM AUTOCLAVE ENABLES IMPREGNATION OF ROOF FRAMEWORK
The range of spray impregnators now includes the new IMP-PG “Oscillating” model. This vacuum autoclave enables the impregnation of roof framework placed in properly braced packs.
The application and use of the IMP-PG is equipped to give wood protection against the following Risk Classes:
Risk class 1
: situation where the wood or wood based product is shielded, completely protected from atmospheric agents and not exposed to humidity.
Risk class 2: situation where the wood or the wood based product is shielded, completely protected from atmospheric agents, but where high environment humidity may cause occasional but not persistent humidity.
Risk class 3: situation where the wood or the wood based product is not shielded and is not in contact with the ground. It is continuously exposed to the atmospheric agents or, even though protected from them, is subjected to frequent humidity.
In these three cases, defined by ENC, (European Normalisation Committee), IMP-PG guarantees protection and long lasting esthetical quality of the wood.

THE TREATMENT OF ANTIQUE FURNITURE INFESTED WITH XYLOPHAGES, SUCH AS WOODWORM OR OTHER BEETLES
Among the special applications the IMP-PG is employed in is the “treatment” of antique furniture infested with xylophages, such as woodworm or other beetles.
The furniture is partially disassembled and placed on the trolley frames. Once the load is complete, the material is positioned in the autoclave for treatment using special products.
In this phase, thanks to the combined action of the vacuum and the atomisation of the repellent, penetration of the treating agent is very high and is able to penetrate into the most difficult parts to reach of the furniture.
The elimination of woodworm and other insects guarantees the long life of the element without altering its structure or natural beauty.

USE OF IMP-PG IMPREGNATING PLANTS
EXAMPLES OF USE

– treatment and coating of doors, windows, storm windows, shutters etc…
– treatment and coating of articles for use outdoors
– treatment of matchboard
– treatment of models
– coating wooden toys
– wooden items and accessories
– turned items
– in substitution for dip coating

– antique furniture, treatment and prevention
– treatment of daises

CONCLUSIONS
The purchase of an IMP-PG plant allows small to medium sized carpentry companies to face and brilliantly resolve the problem of treating and coating with solvents and water.
As an example, using model IMP-PG 2400/4500 40 windows a day made up of wings plus the frame (either assembled or disassembled) can be treated.

The complete cycle is as follows:
– application of a first coat of clear or coloured impregnant
– application of a second primer/finish coat
The plant is equipped to use mono-component impregnants or paint as long as they are sufficiently fluid. The maximum viscosity for correct operating must not exceed 25-30″, measured using a 4mm diameter COPA FORD.
When using water based impregnants or paint we suggest version A.C (anti-corrosion) where the internal surfaces of the autoclave have been treated with epoxy paint and mechanical parts and conduits are rust proof.
